摘要
为有效感知网络吞吐量变化、时延以及丢包等态势,科学地量化分析网络性能,提出基于时间域的主动式通信网络性能自动化监测方法。构建基于时间域的三级网络性能自动化监测结构,依据网络通信目的、分布式监控以及集中控制节点采集网络监控数据,将吞吐率、时延、丢包率作为衡量主动式通信网络性能的时间域指标,通过网络吞吐率、时延与时延抖动计算以及基于EM-MLE算法的丢包率计算,实现网络性能自动化监测。经实验验证:该方法针对网络吞吐率、丢包率与时延监测结果均与实际情况较为接近,能精确监测不同月份网络链路的可用率与优良率变化。
In order to effectively sense the situation of network throughput change, delay and packet loss, and scientifically quantify the network performance, an active communication network performance automatic monitoring method based on time domain is proposed. According to the purpose of network communication, distributed monitoring and network monitoring data collected by centralized control nodes, the throughput, delay and packet loss rate are taken as time domain indicators to measure the performance of active communication network. Through the calculation of network throughput, delay and delay jitter, and the calculation of packet loss rate based on EM-MLE algorithm, it realizes the automatic monitoring of network performance. The experimental results show that the monitoring results of network throughput, packet loss rate and delay are close to the actual situation, and can accurately monitor the changes of availability and excellent rate of network links in different months.
